Cannot create clusters from an existing network

[nguyenhuukhoi]

Hello. I am using magnum_cluster_api 0.24.0 and openstack 2024.1.

I cannot create cluster and this is error from capi:

"Failed to apply patch with uid "cc66bd0c-4baf-4786-9976-b0813685c861": error applying json patch (RFC6902): [{"op":"add","path":"/spec/template/spec/network/name","value":"privatenetwork"}]: add operation does not apply: doc is missing path: "/spec/template/spec/network/name": missing value" controller="topology/cluster" controllerGroup="cluster.x-k8s.io" controllerKind="Cluster" Cluster="magnum-system/kube-4nicv" namespace="magnum-system" name="kube-4nicv" reconcileID="522df2a3-04ad-451e-8dd8-8f269f33de97" patch="auditLog" patch="openidConnect" patch="bootVolume" patch="ubuntu" patch="flatcar" patch="clusterConfig" patch="controlPlaneAvailabilityZones" patch="newNetworkConfig" patch="existingFixedNetworkNameConfig" uid="cc66bd0c-4baf-4786-9976-b0813685c861"

Could give me some advices for this bug? Thank you.

If we choose existed network then we cannot create cluster but we can do it by let system create the fixed network.

After correct patch existingFixedNetworkNameConfig. I encounter this error:

reconcile_state.go:1342] "Failed to create object" err="OpenStackCluster.infrastructure.cluster.x-k8s.io "kube-ahqap-cm5qf" is invalid: [spec.managedSubnets[0].cidr: Required value, : Invalid value: "null": some validation rules were not checked because the object was invalid; correct the existing errors to complete validation]" controller="topology/cluster" controllerGroup="cluster.x-k8s.io" controllerKind="Cluster" Cluster="magnum-system/kube-ahqap" namespace="magnum-system" name="kube-ahqap" reconcileID="224fea6a-6cf2-4885-bca1-e62e3e2f7f72" OpenStackCluster="magnum-system/kube-ahqap-cm5qf" OpenStackCluster="magnum-system/kube-ahqap-cm5qf (edited)
